WHY ANGLERS CHOOSE BIGBLUE: * Real-Time Ocean Intelligence Don’t rely on outdated data. BigBlue delivers the most comprehensive satellite scans available: Ocean temperature reported by scientific Sea Surface Temperature (SST) sensing satellites: 9 daily scans from MODIS, VIIRS, and GHRSST satellites. Chlorophyll Charts: Identify clear water boundaries and plankton-rich feeding zones (6 daily sources). True Color Imagery: See real ocean conditions, current edges, and debris lines. * Global 3D Bathymetry & Structure Fish live where the structure is. Our high-resolution global bathymetry maps reveal seamounts, canyons, ledges, and drop-offs worldwide. Combine structure data with temperature breaks to pinpoint productive waters/ * 100% Offline Capability (No Signal? No Problem) BigBlue is built for offshore use. The app automatically caches data as you view it. Simply pan over your fishing grounds while on Wi-Fi, and all charts, temp layers, and bathymetry are saved to your device.

Just saying “in app purchases” is not the same thing. There is no free access to this app. Apple really needs to crack down on this shenanigans. ### 1/5 — Paywall *2025-03-19* Is this app no longer free? Everytime I open it now I’m blocked from using it by a paywall screen that cannot be deleted, although there is nothing in the app store page to indicate “offers in-app purchases”. What happened?!? 😭 goes from useful to useless! ### 5/5 — Great App *2024-08-21* I’m really enjoying the app with the ease of use between each feature. I’m still learning how to use each, but the temperature feature has been great. It’s helping me find the best zones for tuna. I just now gotta land them. ### 1/5 — Not what I was expecting *2023-12-21* I purchased this app thinking I would get up to date data but it would only give 4day old data. Not worth the $22 a month. ### 5/5 — Incredibly useful tool *2023-07-30* This is one of the best tools for divers or fisherman. Cannot recommend it enough. Useful information, easy to use interface. Outstanding product. ### 5/5 — Amazing Fishing App! *2023-04-20* I’ve tested and used many many fishing apps and sites looking for an edge hunting for billfish. This one is a whole new level of quality. It combines very useful navigational features with high definition ocean intel. There may be a more useful app for billfish but I haven’t found it yet. 100% recommend to all serious fishermen ### 5/5 — Love the data, cleanly displayed *2023-04-18* It's a big ocean, and I'm tired of burning fuel trying to guess where the school we saw last week has gotten to. A buddy recently turned me onto some of the science around surface temps and bathymetry. I'm pumped to give this a try next time out. Seems really user friendly so far planning from land. ### 5/5 — Fish Smart, not blind! *2023-04-18* This is a great app for charting water temps and Chlorophyll density to help locate the most productive fishing waters. You have an option to select various temperature models, and the fish guide is a perfect tool to help identify the best areas to fish based on temp and chlorophyll. Save time and fuel and fish smart with this lightweight, simple, and powerful app! ### 5/5 — Essential for tournaments *2023-04-17* GeoPelagic is an incredible tool for planning offshore trips and fishing tournament strategy. It has the best data and interface of all the fishing apps I have. The speedometer and live updating distance to waypoints are handy. The track of where I’ve been on the chart is very helpful. The premium account is definitely worth it - saves me time and fuel out there. My only complaint is that it takes a pretty experienced angler to figure out how to use it well, not for rookies but can make a good captain great. 5 stars. ### 5/5 — All the tools you ever need to sport fish right here *2023-04-15* I always knew water temp was the best way to find the fish that I was seeking however with this app you can even take into account things like chlorophyll concentration and avoid areas that might be too chlorophyll dense and impacting visibility. You can chart a course in the app and can even get data for across the whole globe - other apps are limited to what regions it covers. Download it now and you’ll have the only tool you need to find the fish. ## Frequently asked questions about BigBlue Offshore Fishing ### What is BigBlue Offshore Fishing?
